four computers on same unmanaged switch can't copy files between them - GEEK squad couldn't fix after 3 hours of attempts

Since 24H2 I'm in sort of the same boat. Can't see one of my NAS devices, some of my PCs aren't there and worst of all the 24H2 PC doesn't see itself in the network!! Now that's just insane to me and this alone has kept me from updating any of my other PCs to 24H2.

Insane, I agree. But it is what we got.. The solution to most issues for folks with mixed OSes is to create credentials on every machine for access
to every other machine. It does not matter if you use the same MS account for every one of them, you still have to build credentials in credentials manager.

I worked for days trying everything I could find until I gave up. I managed alright using RDP. (all my machines are PRO).
Fast forward about 6 months and I upgraded my last system from 10 to 11. Every system saw all the others, all my credentials worked. But I still couldn't access a NAS. I got it worked out using Chatgpt. First problem I ever used AI to solve.

The NAS seems to always be the one that is the stickler. All our networked machines are now Win11 Pro, and I do use RDP for a couple of them that are headless. My NAS is a somewhat aging Netgear ReadyNAS, and it always takes the full suite of changes to allow full access when I do a new install.

Mine is pretty ancient, it's next on the replacement list. I enabled everything I could, which is not much on this model. Mine is the ReadyNAS 102 from 2013, so it's twelve years old. To give you and idea of the age, it still has an eSATA port if you want to put an external disk on it! I have a USB 3 disk on it to do automated backups of the data. The firmware is 6.10.10, the last release and it's listed as end of life. I don't think I'll be getting any updates to the firmware. :LOL: It really is time to replace it, just another thing on the list.

You've already done some of this, but this is what you need in order to see other computers in the network node of Explorer.
  1. Set network profile to private. (not strictly needed, but using Public is not a good idea)
  2. Enable Network Discovery for private networks.
  3. Make sure the services "Function Discovery Provider Host" and "Function Discovery Resource Publication" are set to Manual start, and the services they depend on are enabled.
  4. Make sure the firewall rules for function discovery are enabled.
For items 3 and 4, you can run the attached PowerShell script to get a report. No need to run it with admin rights; it's just showing you the state of things. Rename it to a .ps1 extension before trying to run it. You should get something like this; I edited mine to make it shorter.

Code: 
The following services should be set to a start type of Automatic or Manual:

Name         DisplayName                              Status StartType
----         -----------                              ------ ---------
DcomLaunch   DCOM Server Process Launcher            Running Automatic
http         HTTP Service                            Running    Manual
fdphost      Function Discovery Provider Host        Running    Manual
FDResPub     Function Discovery Resource Publication Running    Manual


The network category for your connection should be Private:

Name    InterfaceAlias    NetworkCategory
----    --------------    ---------------
Banana  Pineapple         Private


The following rules should be enabled and set to allow traffic.

DisplayName                              Direction Enabled Action
-----------                              --------- ------- ------
Network Discovery (SSDP-Out)              Outbound    True  Allow
Network Discovery (WSD Events-In)          Inbound    True  Allow
Network Discovery (UPnP-Out)              Outbound    True  Allow
